"Every addition the States receive to their number of slaves tends to weaken and render them less capable of self-defence. In case of hostilities with foreign nations, they will be the means of inviting attack instead of repelling invasion. It is a necessary duty of the General Government to protect every part of their confines against danger, as well internal as external. Every thing, therefore, which tends to increase danger, though it be a local affair, yet, if it involve national expense and safety, becomes of concern to every part of the Union, and is a proper subject for the consideration of those charged with the general administration of the Government." And we hear, too, a great deal about war, civil war, if this unhappy controversy is not satisfactorily adjusted, which means upon the terms proposed by the slave States. But do gentlemen mean that an appeal will be made to the sword, unless the Constitution shall be so amended as to "provide that slavery of the African race shall be effectually protected as property in all the territory of the United States, now held or hereafter acquired south of latitude 36 deg. 30'"?--which is the proposition of Virginia. If that is what is meant, then let me, before I close, read an extract from one of the last speeches made by HENRY CLAY in the Senate of the United States. It is as follows: "If, unhappily, we should be involved in war, civil war, between the two portions of this Confederacy, in which the effort upon the one side should be to restrain the introduction of slavery into the new Territories, and upon the other side to force its introduction there, what a spectacle should we present to the astonishment of mankind, in an effort, not to propagate rights, but--I must say it, though I trust it will be understood to be said with no design to excite feeling--a war to propagate wrongs!" Mr. HOWARD moved an adjournment. Mr. BRONSON objected, raising the question of order. He claimed that the Conference, by adopting the resolutions of Mr. RANDOLPH, had fixed the limits of the sessions, from 10 o'clock A.M., to 4 o'clock P.M. The motion of Mr. HOWARD was not concurred in.
